SPECIFICATION formingpart of Letters Patent No. 398,148, dated February 19, 1889.

Application filed September 27, 1888. Serial No. 286,612. (No model.)

T0 LZZ whom 'L' may concern:

Be it known that l, JACOB l-IAIsH, a citizen of the United States, residing at De Kalb, in the county of De Kalb and State of Illinois, have invented certain new and useful lmprovements in Vehicles; and l do hereby declare the following to bc a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it l appertains to make and use the same, reference being had to the accompanying drawings, and to letters or Iigures of 'reference marked thereon, which form a part of this specification.

My invention has reference to improvements in vehicles, and pertains more especially to the construction of the hub of the wheel, mode of seating the spokes therein, and the conformation of the spindle or end of the axle.

The objects of my invention are, iirst, provision for seating the spokes in a dovetailed form in the hub, and to drive said spokes into position sidewise, as distinguished from the usual end driving, whereby it is practicable to give the inner end of the spokes a dovetailed formation to certainly secure them against casual withdrawal; second, to reduce the bearing-area between the axle-spindle and the hub, to place such bearing-points at t-he extremities of the hub, and provide a means of automatically oiling such bearing-surface from a central oil-receptacle; third, to provide such central oil-ehamberg fourth, to give the periphery of the spindle such a conformation as that the rotation of the wheel will tend to force out at the end of the hub any dirt or foreign substance that may casually ind access thereto, and, iii'th, to substantially seal the end of the hub against any casual escape of,

the lubricating-oil within it.

ln the drawings, Figure 1 is a perspective of a hub containing my inventionV in position upon the axle. Fig. 2 is a longitudinal central section of the saine. Figs. 3 and 4 exhibit in section two modified forms of diagonal grooves in the periphery of the spindle. Fig. 5 is the same as Fig. 1, except that the hub in Fig. 5 is shown adapted to receive a double series of spokes. Fig. 6 is a longitudinal central section of the construction shown in Fig. 5, and also exhibits the form of wrench used to place or remove the end caps. Fig. 7 is a perspective of the axle-spindle with the series of spiral grooves formed in its periphery. The forml of grooves shown in Fig. 7 is that which I have adopted, although the modied configuration shown in Figs. 3 andflC will operate nearly or quite as well. Fig. 8 is a view of the outer end of the hub when closed and in position on the axle, with the center of cap M removed, showing cap Il. Fig. 9 is a view of the same with the end caps, M and H, removed. Fig. 10 is a cross-section in the line cc oc of Fig. 2. Fig. 1l is a modified form of the construction shown in Fig. 2, with the interior of the hub centrally enlarged and a portion of the shell of the spindle cut away, exhibiting diagonal ribsl formed on a portion of the interior of said shell to assist in holding the same on the end of the wooden axle. Fig. l2 is a longitudinal central section of the hub, showing the central oil-recessin a concave form.

Referring to Fig. 2, where the parts are shown in their mutual relation, A is the end of the wooden axle inserted in the metallic skein or pipe B, and held in place therein by the end screw, C, which latter is seated by being screwed into the end of the axle A, and by having screw-threads l formed on the periphery of its head conformable to like threads 2, formed on the interior wall of the skein B.

D is the hub, which is cut in two transversely near its center, thus forming the in= ner end, D', and the outer end, D2.

E is the inner end of the spokes, having a dovetailed conformation adapted to enter and ill the dovetailed recess, F, formed in the hub D.

G is the pipe-box lining the interior of the hub D, and is provided at its inner end with the external annular flange, G', Fig. 2, to form a shoulder for the inner end of said hub.

The interior cap, H, provided laterally with the annular head or flange 3 at its outer end, is also provided with thread 4, formed on the periphery of its interior portion or stem, and

is thus adapted to be screwed into thread 2 recess N.

serves the double function of holding t-he hub l.) on the skein B, and also seals the interval between said skein and pipe-box G, against the escape of the lubricating-oil. An annular recess, 5, adapted to receive a rubber ring, 13, is formed in the outer face of the annular flange on the inner end of the skein B, ad- K jacent to the .flange G of the box G, and I serves to prevent the escape of the lubricating-oil at the inner end of said hub.

On the exterior of the outer end of the pipebox G is formed a screw-tl1read, 7, and a ring, J, having conformable threads in its interior wall, is screwed upon the thread 7, and serves to hold the two halves of the hub D together.

K is the inner hub-band, and L the outer i one. In the inner wall of the outer hub-band, L, there are formed screw-threads S and cap M, having like screw-threads 9 formed on its periphery, is thereby screwed into the end of the outer-band, L, and eifectually seals the end of the hub against the admission of any dirt thereto.

Recesses 1l., Fig. S, are formed in the outer surface of the interior cap, H, and exterior cap, M, and by means of a wrench, O, of the conformation shown in Fig. (l, .'aid caps can be seated or removed.

The ends lO of the walls of the pipe-box G, Fig. are thicker than its central portion, resulting in the formation of the elongated oil- ',lhe oil is placed in said recess either before the wheel is put ou the axle or it can be admitted thereto by means of the usual opening through the hub D, or in any other lobvious mode.

By reason of the form of central recess, N, the ends lO are the onlyportion of the box G,

which supports the axle A, thus reducing the amount of the usual friction.

Then the vehicle is stationary, the oil will collect by its own gravity in the bottoni of the oil-recess N.

Each series of spiral grooves l" on the exterior of the skein or spindle B is formed reversely of the other, Fig. 7 and in the rotation of the hub D serve to force or carry the oil from said oil-recess to and from each end of the hub D and to and from the bearing portions aforesaid. The oil passes outward in one series of said grooves and the excess inward in the other series. Thus a constant circulation of oil is maintained over the bearing-surfaces of said spindle. Thus oil sufficient for a long period of usage can be primarily stored inthe oil-recess N.

The advantage of making the hub D of the two parts D and D2 consists in the fact that thereby the inner ends of the spokes E may have the dovetailed formation to it the dovetailed recess F in said hub, and said spokes can beforced sidewise into said recess before the two parts D and D2 are brought together. In the construction of the wheel the outer ends of the spokes may be iirst seated in the felly and the inner ends of said spokes subsequently forced laterally into position in the hub D, as aforesaid, and after the ring J is driven to it-s seat it is impossible for the spokes E to be drawn from the recess F.

The spokes E may all be seated in. the part D', as shown in Fig. l, or may alternate in the parts D and D2, as shown in Fig. 5. The inner ends of the spokes E may be readily formed by machinery.

The form of hub shown might be adapted with obvious changes to be used upon an iron axle.

Thethicker ends l0 of the box G may, if preferred, consist of interior bands driven into the ends of said box.

By forming the hub D of two parts, as shown, it is feasible to use a box, G, having a swelled -or enlarged center, as shown in lf2, in which event the oil-recess N will be concave in form.

that I claim as my invention, and desire to secure by Letters Patent of the United States, is-

l. The combination of the parts D and D2, 011e O1 both of said parts being provided with dovetailed recesses F, spokes E, provided with conformable dovetailed inner ends, adapted to be moved laterally into said recesses F, pipe-box G, provided with external annular ange G with exterior thread, 7, and with thickened ends 10, ring J, provided with interior threads, 1.2,and the skein B, provided with peripheral spiral grooves P, substantially as shown, and for the purpose described.

The combination of the skein B, provided with the interior end threads, 2, and with the flange and annular recess 5 therein, the rubber ring 13, thecap H, provided with flange 3 and threads 4L, and hub D, provided with the pipe-box G, substantially as shown, and for the purpose described.
